Troubleshooting
This chapter describes items to check if the system does not function as you expected, and meaning and handling of the
warning messages.
Incorrect use might prevent this system from providing primary performance even though the system is not damaged. If a
symptom such as those in the following table occurs, take action as described in the table before requesting repair.
If a problem that is not listed in the table occurs or if a problem that occurred is not resolved by taking action as described
in the table, disconnect the power cable of the device, and then contact your nearest Nikon representative.
Note that the tables in the following subsections cover only issues on operating the DS-L4 and a microscope camera. For
issues on using the DS-L4 connected to the Nikon microscope, refer to the separate volume of this manual, "Microscope
